# Mugi End User License Agreement (EULA)

**Version 0.9.0 — Public Preview (June 2026)**

**Last updated:** June 2026

By installing or using Mugi (the “Software”), you agree to this End User License Agreement.

## Important Key Terms

This is a **regular proprietary software license agreement**. All copyrights and other intellectual property rights in Mugi are retained by the developer. The Software is currently closed-source. You are granted only the limited rights described in this Agreement.

**We are not responsible for any data loss or any other kind of damage** that results from using the Software. The Software is provided “AS IS” and without warranty of any kind. This includes (but is not limited to) permanent loss of data if you use the optional chat encryption feature and later lose access to your encryption key.

**Mugi collects and transmits NO PERSONAL DATA.** The developer of Mugi collects no personal data. No information about you, your conversations, your notes, your files, or your activity is transmitted off your Mac to the developer or to any service operated by or on behalf of Mugi. All data stays on your machine. You retain full ownership and all rights to your personal data.

## 1. Grant of License

Subject to your acceptance of this Agreement, the developer grants you a limited, non-exclusive, non-transferable, revocable license to install and use the Mugi macOS application and the local services it runs (the “Software”) on your Apple-branded computer(s) for your personal, non-commercial use only.

The license covers the full product, including the native SwiftUI macOS app and the local Python backend and services it launches.

## 2. Copyright and Ownership

The Software, including all copies and all intellectual property rights in it, is and remains the sole property of the developer. All rights not expressly granted by this Agreement are reserved. The Software is proprietary and closed-source; the source code is not licensed or provided to you.

## 3. Privacy and Your Data

The developer collects **no personal data**. No usage data, conversations, notes, files, or other personal information is sent to us or to any Mugi-related service (unless you voluntarily configure the Software to use an external large-language-model provider that you choose).

All data created or used by the Software remains on your Mac. You are solely responsible for backing up your data. The optional encryption feature means that if you lose your encryption key, your data may become permanently inaccessible — we have no way to recover it.

## 4. Disclaimer of Warranties

THE SOFTWARE IS PROVIDED “AS IS” AND “AS AVAILABLE,” WITHOUT ANY WARRANTY OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO THE IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT.

We do not warrant that the Software will be uninterrupted, error-free, secure, or that defects will be corrected.

## 5. Limitation of Liability

TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, THE DEVELOPER SHALL NOT BE LIABLE FOR ANY DIRECT, INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, PUNITIVE, OR EXEMPLARY DAMAGES (INCLUDING, WITHOUT LIMITATION, DAMAGES FOR LOSS OF DATA, LOSS OF PROFITS, BUSINESS INTERRUPTION, OR ANY OTHER LOSS) ARISING OUT OF OR RELATED TO YOUR USE OF OR INABILITY TO USE THE SOFTWARE, WHETHER BASED ON CONTRACT, TORT (INCLUDING NEGLIGENCE), STRICT LIABILITY, OR ANY OTHER THEORY, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

This limitation applies in particular to any data loss (including from shell commands executed via the agent, file operations, background processes, or loss of encryption keys) and to any other damage resulting from use of the Software.

## 6. User Responsibilities

You are fully responsible for all activity that occurs through your use of the Software, including any commands executed via the shell tool or other powerful local tools, and for the consequences of any file modifications, network requests, or other actions the Software performs at your direction.

You agree not to use the Software for any illegal purpose or in violation of any applicable law.

## 7. Restrictions

You may not:
- Reverse engineer, decompile, disassemble, or create derivative works of the Software (except to the limited extent such restrictions are prohibited by applicable law).
- Sublicense, rent, lease, lend, sell, or otherwise transfer the Software or your rights under this Agreement.
- Use the Software for any commercial purpose without separate written permission from the developer.

## 8. Updates to the Software and This Agreement

The developer may release updates to the Software. Such updates are subject to this Agreement or any updated version of this Agreement that accompanies the update.

The developer may update this Agreement from time to time. Material changes will be posted on the website (mugi-ai.com/agreement) and/or within the application. Your continued use of the Software after an updated version of this Agreement is posted constitutes your acceptance of the changes. The current version of this Agreement will always be available at mugi-ai.com/agreement.

## 9. Termination

This Agreement and the license granted to you will terminate automatically if you breach any term of this Agreement. Upon termination, you must cease all use of the Software and delete all copies in your possession.

## 10. Governing Law

This Agreement shall be governed by and construed in accordance with the laws of the State of California, United States of America, without regard to its conflict of laws principles. Any legal action or proceeding arising under this Agreement shall be brought exclusively in the state or federal courts located in California, and you hereby consent to the personal jurisdiction and venue therein.

## 11. Miscellaneous

This Agreement constitutes the entire agreement between you and the developer concerning the Software and supersedes all prior agreements. If any provision of this Agreement is held to be unenforceable, the remaining provisions will continue in full force and effect. You may not assign or transfer this Agreement or any rights hereunder without the prior written consent of the developer.
